7.5 x 6.5 x 5 cm
Ex-Ed David Collection
$550
A gem like 4.7 cm fishtail-twinned, orange, pristine Gypsum crystal on a bed of smaller Gypsum crystals. Very representative of the extraordinary ability of Ed David to select the most aesthetic and best quality specimens. You will not likely find a better specimen of this mineral. Note it still has the Halite association, which is often lost due to dissolution in situ.

Garnet is a group of minerals that have been used since the Bronze Age as gemstones and abrasives. Garnets are most often seen in red, but are available in a wide variety of colors spanning the entire spectrum. The name "garnet" comes from the Latin granatus ("grain"), possibly a reference to the Punica granatum ("pomegranate"), a plant with red seeds similar in shape, size, and color to some garnet crystals.
Six common species of garnet are recognized based on their chemical composition. They are pyrope, almandine, spessartite, grossular (varieties of which are hessonite or cinnamon-stone and tsavorite), uvarovite and andradite (From Wikipedia, the free encyclopedia).
Nice display of well formed isolated dark red Almandine Garnets in Shist.

Zacatecas is known as "la ciudad de cantera rosa" or "the city made of pink stone". A beautiful city on a hill (8200 ft. / 2485 m.) which seemingly grew overnight in the mountains of Mexico . In fact, it was the discovery of Silver in the area and the subsequent mines that were responsible for the quick rise of this city in 1546.
Zacatecas mining operations were one of the main sources of Spanish gold while Mexico was a colony known as New Spain.

"Founded as a railroad-promoted townsite and railhead for the White Pine mines in 1869, the town of Elko has served for generations now as the provincial capital of an enormous cattle ranching empire embracing parts of four states. Sixty years ago Lowell Thomas called Elko "the last real cowtown in the American West," and until about 15 years ago that was still a good thumbnail description. But sophisticated new mining technologies permit the harvesting of microscopic particles of the precious metal from mountains (literally) of rock and dirt hauled 200 tons at a time to the crusher. Half a dozen large mining operations produce millions of ounces of gold a year in the region, and even though mining is now on the wane, their impact has transformed the old cowtown into a prosperous young city"
